A Trojan horse dubbed "Zlob" (also known as dnschanger) has been discovered, according to researchers. This virus can attack victims' Internet routers and monitor their network traffic. Researchers pointed out that after a victim's Windows system is infected, the Zlob Trojan attempts to guess the router's username and password combination. If successful, the Trojan changes the DNS of the victim's router, allowing all network traffic to be monitored. Researchers had warned long ago that one day malware would pose a threat to router products, and Zlob is the first Trojan discovered with this capability.
